I'm not quite sure, but have you set DisplaySize to something that's 
1.6:1? Like this perhaps:
Section "Monitor"
	Identifier   "Monitor0"
	ModelName    "Samsung SyncMaster 216BW"
	DisplaySize  480 300
EndSection

If you use a 1.6:1 mode, the apps that pay any attention will now know 
the pixels are square.

Another trick: tell X your monitor's smaller than it really is, and 
things will be drawn bigger. Try:
         DisplaySize 336 210
The opposite also works:
	DisplaySize 560 350
will draw things smaller.

Cheers,

John.
